Efficacy and Potential Mechanisms of Umbilical Cord-Derived Mesenchymal Stem Cells in the Treatment of Ischemic Stroke in Animal Models: A Meta-Analysis

Resumo original em inglês

O que aconteceu

Umbilical cord-derived mesenchymal stem cells (UCMSCs) have emerged as a promising treatment for ischemic stroke. This study aimed to evaluate the therapeutic efficacy and potential mechanisms of UCMSCs in treating ischemic stroke.

A systematic search of PubMed, Web of Science, and Embase was conducted up to April 25, 2024. Literature was screened based on the PICOS principle, with predefined inclusion and exclusion criteria. Relevant data were extracted and analyzed using Review Manager 5.4.

O que encontraram

Out of 1390 retrieved articles, 30 were included in the meta-analysis. UCMSCs significantly reduced infarct size and volume, improved neurological deficit scores, and facilitated neurobehavioral recovery. UCMSCs treatment also modulated inflammatory cytokine levels in brain tissue and serum, promoted microglial polarization, inhibited apoptosis, and increased vessel density in the peri-infarct tissue.

Por que isso importa

UCMSCs administration significantly promoted the neurological function recovery after ischemic stroke. Their mechanisms of action may be related to immune response regulation, inhibition of apoptosis, and promotion of angiogenesis. These findings provide theoretical guidance for improving the quality of basic research and clinical translation.
